• Italian and Jean-Philippe Gbamin could make home debuts• Silva: New signings must learn fast to get in starting line-upMarco Silva said Everton signed Moise Kean to play at centre-forward only and all recruits must “learn fast” to force their way into his starting lineup.The Italy international and fellow summer signing Jean-Philippe Gbamin could both make their home debuts against Watford on Saturday having appeared as substitutes in the Premier League opener at Crystal Palace. Kean, signed in a £29m deal from Juventus, has played out wide for his former club and his country but Silva insists the 19-year-old will be considered purely as a central striker at Everton along with Dominic Calvert-Lewin and Cenk Tosun.
